RADIATOR-COOLING- ATTACHME-NT.

Application filed May 10,

To all whom it may concerm Be it known that I, LOYAL A; MICI-IAELS, a citizen of the United. Statearesidingat Ottumwa, in the county of Wapello' and State of Iowa, have invented certain new and useful Improvements in Radiator-Cooling Attachments, of which the following is a specification. I

In carrying out the present invention, it is my purpose to provide a radiator cooling attachment for motor vehicles, wherein the same is provided adjacent its front side with a plurality" of air inlet holes, together with means for directing the air into said holes, whereby the water in the radiator is additionally cooled while the vehicle is in motion.

The primary object of the invention is to provide such a cap that is not only useful for the above purpose, but the nature of the same is such as to provide a somewhat ornamental form of radiator cap to enhance the beauty of the vehicle.

A further object of the invention resides in the provision of such a cap for radiators that is comparatively simple of construction, and one that may be manufactured and marketed at relatively small cost.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the drawing.

In the drawing:

Figure 1 is a front elevation, partly in cross section of my improved cap.

F igure 2 is a top plan View thereof, and

Figure 3 is a detail transverse cross section taken substantially upon the line 33 of Figure 1.

Referring to the drawing in detail, my improved cap embodies a relatively elongated cylindrical portion 5 of suitable diameter open at its lower end, and formed with an enlarged skirt portion 6, that is provided with screw threads 7, in this instance, the same being as shown upon the outer side of said skirt portion, it being of course understood that in the future practice of this invention, these threads may be withinthe 0 skirt portion for obvious purposes.

The cylindrical portion 5 is provided with a vertical transverse partition plate 8 for dividing the same into front and rear compartments and formed upon the front side of the said partition 8 as more clearly shown 1923. "Serial Nb. 637,932.

in Figure 3,-is a pairofforwardly and outwardly convergent vertical. partition plates ,9; Between the partition plates:9,,the front sidev of the cylindrical portion 5 is formed with spaced vertical rows of openingslO,

these rows being preferably three in number, and the'openings of the central row being relatively larger than thoseof the side rows as shown in Figure '1.

Between the ends of the partition wall 8- and the walls 9, the said cylindrical portion 5 is further provided with circumferentially extending vertical rows of. slots 11, these slots aswell as the openings 10 adapted for permitting a charge of air to enter the cylindrical portion and pass downwardly into the radiator to assist in cooling the water of the engine :when the caris in motion.

The partition plates 8' and 9 divide the interior of the cylindrical portion 5 into a plurality of vertical channels to provide for the thorough circulation of air through the cylindrical portion. In cases where a vehicle is provided with this attachment and is travelling in a direction at right angles to the direction of the wind, it will be observed that the air circulation from the forward to the rear portion of the sleeve will be effected the radiator, the other partition 9 serving to permit the exhaust of the air from the radiator through the openings 11, as well as the openings 15 in the upper end of the rear portion of the sleeve. It will thus be seen that thorough ventilation through the sleeve is provided without regard to the direction of the air circulation around the vehicle.

Formed integrally upon opposite sides of the cylindrical portion 5 are vertical fins 12, which extend upwardly beyond the upper end of thecylindrical portion, and are joined integrally by a connecting portion 13. These fins 12 are slightly curved forwardly as shown in Figures 2 and 3 and are adapted for directing the air currents inwardly towards the slots 11 when the car is in motion. a

The upper end of the cylindrical portion 5 rearwardly of the connecting plate 13 of the fins 12 is provided with openings 1 which will permit the discharge of the heated; air from the radiator. ---The lower end: of the cap, which engages within or over the filler neck of the radiator, is equipped with a removable screen 15, for preventing the entrance of large particles of dust, insects or foreign -matter into, the radiator.

In view of the above description, it will be at once apparent to those skilled in the art that I have provided a highly novel form of cap for vehicle radiators, and one that will effectively function as above described, andreven though I have herein set forth the most preferred embodiment of the invention, it is nevertheless to be understood that -minor changes may .bemade therein, without departing from the .spirit and scope of the invention as claimed.

Having thus-described my invention, what -I claim as new, and desire to secure by Letters Patent, is:

1. In a radiator cap of the class described, a cylindricalportion and a skirt portion, a partition within the cylindrical portion for dividing the same into front and rear chambers, said front chamber being, provided with openings for permittin the entrance of air into the cap, means for directing the air into said openings when the car is in motion, said means comprising a pair of laterally directed fins upon opposite sides of said cylindrical portion.

2'. In a radiator cap of the class described, embo'dying'a cylindrical portion, a partition wall within the cylindrical portion for dividing the same into front and rear chambers,

partition walls within the front chamber for dividing this chamber into a plurality of compartments, openings formed in the front sideof said cylindrical portion, and means for directing air into the openings as the car is in motion.

3. In a radiator cap of the class described,

upon opposite sides of said cylindrical po'rtion. H

In testimony whereof I affix my signature.
